Does the climate change after a tsunami?

Answer 1

There is little reason for a tsunami to change the climate. Climates are affected by changes in the distribution of warm and cold air. Tsunami don't do this. Tsunami are caused by undersea earthquakes and these generate an insignificant amount of heat, made even more insignificant by the huge heat capacity of the ocean.

For a tsunami to affect climate it would have to be caused by a major volcanic eruption. In such a case, the volcanic activity would get the blame, not the water.

The only way a tsunami might be more closely related to a climate change would be this:

Suppose a tsunami were caused by a huge shifting of the ocean bed and that this caused a major change in an ocean current. That would result in a change in the earth's heat distribution and thus its climate.

But still, it's the earthquake getting the blame for both - the tsunami and the climate change.

Answer 2

In the short term, a tsunami does not significantly affect the climate. However, the impact of a tsunami on coastal ecosystems can have longer-term effects on the local climate due to changes in vegetation, land use, and environmental conditions.
